The winter season is just around the corner, and it is a good time to remind our customers about how to properly prepare rental equipment for inclement weather conditions. This not only applies to when a boiler is in operation, but also when a boiler is down or in transport.
By following the recommended steps below, you can avoid boiler operational difficulties and/or equipment damage during freezing weather conditions:
- Enclose both the front and rear of the boiler area and use an external heat source to minimize freezing conditions.
- Install heat tracing with insulation to protect exposed stagnant water lines.
- Utilize an appropriate heat tracing method (electric or steam tracing) to all of your main lines and piping components. This includes the following lines which should be heat traced regardless if the boiler is in operation or not (in freezing conditions): sensing lines (steam drum to CMR, high steam and steam gauge), auxiliary low-water-cut-off, water column and level control blowdown. Depending on the length of piping runs, the main and continuous blowdown should also be heat traced.
- In addition to heat tracing on stagnant sensing lines, drain the lines and fill them with a 50/50 (water/glycol) solution, making sure to re-connect the line. 5. When an extended boiler down time is expected, completely drain the boiler and stagnant water lines.
- The above lines are considered stagnant lines and should be heat traced regardless if the boiler is in operation or not (freezing conditions).
- Nationwide has also done the following in addition to heat tracing on the stagnant sensing lines: Drain line, fill with 50/50 (water/glycol) solution, re-connect line.
- Depending on the length of piping runs, the main and continuous blowdown should also be heat traced.
- For extended boiler downtime, drain boiler and stagnant water lines completely.
- If rental equipment becomes damaged due to freezing weather conditions, the repair or replacement is the responsibility of the lessee.
The above are recommendations; however, use sound engineering judgment calls when there are concerns of possible freeze damage to the equipment. For further information, give us a call at 1-800-227-1966.
Members of the Council of Industrial Boiler Owners (CIBO), including Nationwide Boiler’s Vice President Larry Day, will be gathering this week in Santa Fe, New Mexico for CIBO’s 36th Annual Meeting. The meeting is held yearly to discuss environmental policy changes in the boiler industry, and the main topic of discussion this year is energy.
Energy is priceless; it is needed for everything we make and everything we do. With the 2014 Clean Power Plan proposal, we may see increased energy costs in the foreseeable future. The agenda for this year will be directly related to energy and the environment, and include:
- Assessment of CIBO’s activities, advocacy, accomplishments and plans for the past year and the strategic direction for the next and future years relative to CIBO’s Vision and Mission;
- Consideration of the energy and environmental questions corporate and institutional CEO’s and Government legislative and regulatory leaders will be asking in the upcoming year;
- Discussion on the broader energy and environmental issues that could be impacting overall corporate operations and planning in the near term;
- Investigating the regulatory and legislative advocacy aspects of major issues to maximize the possibility of positive results for our members and industry as a whole;
- Networking with the top energy and environmental leaders at CIBO member companies and key outside regulatory, technical and legal experts available to provide up to the minute expertise on the important issues considered.
The CIBO annual meeting has brought together members of the industrial boiler industry since 1978 to exchange information relating to energy and environmental practices and policies. CIBO strives to integrate our nation’s energy and environmental policies to attain benefits not just for its members but also for the country.

The importance of implementing plant safety measures is undeniable, especially when exposed to heat processing equipment. Accidents and injuries in industrial plants are common but can be easily avoided if the right precautions are taken.
According to the U.S. Occupational Safety and Health Administration (OSHA), injuries caused by hazardous energy account for 10 percent of accidents in many industries. Hazardous energy is found in electrical, mechanical, hydraulic, pneumatic, chemical, thermal or other sources in machines and equipment. OSHA’s “lockout/tagout” (LOTO) procedures provide guidelines for controlling this hazardous energy when servicing or maintaining equipment.
LOTO requires that prior to any routine maintenance or service on equipment, an authorized employee must follow certain procedures to ensure safety. After the equipment is turned off and disconnected from its energy source, to prevent the release of hazardous energy a lockout or tagout device must be applied to the energy-isolating device and it must be verified that the energy has been isolated effectively.
If the correct safety measures are not taken, the release of this stored energy could cause serious injury. It is highly recommended that employers create a procedure for employees to follow when dealing with potentially hazardous energy.
